United States Patent C VENTILATOR WINDOW George H. Bugenhagen, Minot, N. Dak.

Application April 6, 1953, Serial No. 346,835

2 Claims. (Cl. 20-53) yThe invention relates to a ventilator windor construe tion and more particularly to a ventilator window that may be inserted into the conventional glass block or glass brick structure or window panel by the removal of one complete block.

It is therefore one of the objects of the invention to provide a ventilator window having an outer sash that swings outward at the bottom and an inner sash that swings outward from the window frame at the top.

Another object of the invention is to provide a ventilator window structure in which the inner and outer sash members are linked together mechanically so that both open together.

Another object of the invention is to provide a double sash ventilator window having provision for insertion or ready removal of a screen.

Another object of the invention is to provide frame and sash members of readily formed or extruded members of simple design and readily susceptible of mass production.

Another object of the invention is to provide a ventilator window in which the inner or outer sash may be readily removed from a position inside of the building for repair purposes.

Another object of the invention is to provide a Window construction in which the upper edge of the outer sash is always positioned within the overhang of the frame so as to allow ready drainage of any rain from the above window area.

Another object of the invention is to provide window frame and sash members which may be mitered nearly through at the corners while retaining suicient metal to allow bending around to form a strong joint at the corner.

Another object of the invention is to provide a ventilator window with an integral guard grill to prevent unwanted entry.

Still another object4 of' the invention is to provide a weather-strip that may be readily attached in a novel snap-on manner and retained in position by spring action away from the area where it would be subjectl to direct action of the weather.

Still other objects will be apparent during the following description which taken in connection with the annexed drawings set forth in detail certain means of carrying out the invention, such disclosed means illustrating, however, but several of the various ways in which the principle of the invention may be used.

In the drawings:

Fig. l is a side elevation showing the new ventilator window positioned in -a conventional glass brick window construction.

Fig. 2 is a View in section taken along lines 2--2 of Fig. 1 showing more of the details of construction of the new ventilator window and also showing in dotted lines the inner and outer window sashes in an open position.

Fig. 3 is a fragmentary sectional view taken along lines 3-3 ot' Fig. 2 looking in the direction of the arrows.

Fig. 4 is a fragmentary sectional view showing an irnproved weather stripping for the new ventilator or window.

Fig. 5 is an enlarged fragmentary sectional view showing the manner in which the hinge support arms are attached to the window sash.

Fig. 6 is an enlarged fragmentary view showing the detail or the removable corner construction of the sash of my new ventilator window.

Fig. 7 is a fragmentary side elevation of the corner construction of the new ventilator window.v

Fig. 8 is an enlarged sectional view showing a guard grill adapted to be used with my new ventilator frame.

Fig. 9 is a general view showing the detail of the guard grill.

Referring to Fig. 1 my new ventilator window designated generally by numeral 1 is positioned in a glass brick window construction as indicatedv by the mortar joint pattern 2 surrounding the ventilator window.

In Fig. 2 the window frame comprises an extruded or shaped member 3 provided with a centrally located inwardly extending T-shaped element 4. The portion of the frame toward the outside ends in a knob 5 and is provided with a sash stop 6 which engages the outer window sash 7. The outer sash 7 is of modified channel shape and mounts glass 8 within the channel mouth. The glass pane 8 may be secured in the sash as by glazing 9 or by the use of the conventional rubber or composition sealing strip. The channel portion of sash 7 has integral therewith an inwardly extending leg 10. A suitably positioned hole 11 receives one end 12 of coil spring 1,3` while the other end 14 of the coil spring is hooked around T-member 4. The end 14 of the coil spring 13,v is formed to extend slightly beyond the face of. Trnember 4v at 15 and thus forms a yieldable retainer for screenframe 16 when the latter is pressed past the extending end 1,5- of the spring end. As seen the coil springs 13 are connected to each sash and also serve to help return thewindows to a completely closed position. The screen frame 16 of modified channel shape supports screen 17 which is held in the frame as by yieldable. compressedV clip element 18. The portion, of frame 3 towards the inside. of vthe window ends in a rounded knob 19 which is adapted to carry weatherstrip 20 (see Fig. 4f). Weatherstrip 20v seals against inner window sash 21 carrying glass 22. The inner sash 21 with outstanding leg 23 is of similar construction to outer sash 7 andthe glass pane is similarly mounted. A second coil spring is mounted similarly4 to coil spring 13, is identical therewith, and serves'an identif cal purpose. A manual control closing and openinghandle 24 is mounted on inner sash 21. The stop 6 may be suitably perforated as at 25 to allow drainage of. water which may collect inside the frame when the window is in an open position during a rainstorm;

One of the sash supporting and actuating members comprises a plate member 26 rotatably mounted on pin 27 carried by T-member 4. The plate member 26 has two extending arms 28 and 29 integral therewith. Arm 28 extends and is secured at the top to outstanding leg 10 of outer sash member 7 by means of pin or rivet 30 while arm 29 extends and is secured to the bottom of inner sash 21 on outstanding leg 23 as by means of pin. 31. The sash members 7 and 21 are further supported and actuated by a second set of hinge arms which are also mounted on pin or bearing 27. The second set ofl supporting members comprise a central plate member 32 rotatably mounted on pin 27 and carrying extending arms 33 and 34. Arm 33 is hinged on pin 35 with a second arm 36 which is secured towards the bottom ofv sash 7v on outstanding leg 10 by means of rivet or pin 37. Arm; 34 is likewise integral with plate 32 and is hinged on pin. 38 to a second arm 39. The second arm 39 is securedA toward the upper end of sash 21 on outstanding leg 23. If ldesired the hinge arrangements may be supplied on both and of course parallel sides of the frame to provide better support for lthe swinging sashes. The sashes are shown in ay closed position in full lines and in a generally open position by dotted lines. As an added feature thc frame 1 may also carry absorbent pads 40 adhesively or' otherwise applied to the exterior surface of the frame to draw -excess water Afrom the mortar 41 more quickly and thus hasten ,its setting up.

In those instances'fwhere the ventilator window is of larger size it will be desirable to provide a guard bar assemblykdesignated generally by numeral 42 and de- 4scribed more fully yin connection with Figs. 8 and 9.

In Fig. 3 the relation of the center plates 26 and 32 of the sash supporting hinge and the supporting bearing or pin 27 is more readily seen.

In the enlarged detail of Fig. 4 the manner in which the metal weather strip 20 engages the rounded knob 19 of the frame 1 is more readily appreciated. T he weatherstrip 20 may be preferably made of a thin strip of metal formed to the desired shape and possessing a spring action to allow sealing as it engages the sash 21.

In Fig. 5 arm 29 is seen riding on pin 31 and is assembled so that spring tension holds the arm 29 on the pin. The other arm 28 may be riveted on pin 30 during assembly. This method of assembling the sash on the supporting arms allows the arm 29 to be disengaged for more ready insertion of the screen or placement of the window.

In Figs. 6 and 7 the corner construction of the sections of the sashes will be more thoroughly understood. The mitered corner of the sash is secured by angle bracket 43 which is riveted at 44 to one leg 10 of sash 7 and a screw 45 secures the bracket 43 to the other leg of the sash. The use of the angle bracket is only essential at two of the corners of each sash since the other corners may be mitered out and bent around to form a right angle while still retaining enough metal in the web of the channel section making up the sash to still form a strong corner joint.

Figs. S and 9 illustratethe manner in which guard bars can be inserted in the yframe to protect against unwanted entry. The guard grill indicated generally by numeral 42 comprises top and bottom bars 46 and 47 adapted to seat within frame 1. A central rod 4S is connected to bar 46 with a threaded joint 49 and carries a worm 5i) at the other end. The worm 50 engages a worm gear 51 adapted to be actuated by a key inserted at opening 52 ulation of the handle 24. To provide for ease of removal of the sashes 7 and 21 so that the window panes may be renewed in case of damage the linkage arms 28 and 29 may be slidably mounted on their respective pins carried by the sash. In this way the desired arms may be sprung from the pins so that the plates 26-32 may be lifted and access may be had to the window pane by removal of the sash and releasing the angle brackets at the corner of the sash.

By the improved construction described a ventilator window is provided that may be readily weatherstripped and at the same time the weatherstrip is protected from the weather when the window is in the open position by virtue of the arrangement of the outer window with its top within the overhang of the frame. At the same time the arrangement of the dual window creates a baffle effect so that the current of air entering the room is diverted upward without creating an excessive draft on the occupants of the room.

It will be apprehended that while the ventilator window has been described for use in connection with glass bricks it can also be suitably used in connection with large windows constructed of either wood or metal.

I claim:

l. In a ventilator window the combination of a frame; an inner and outer sash mounted for synchronized swinging movement in said frame; a stop member carried by the frame adapted to engage the outer sash when the latter is in a closed position; a pivot pin mounted on the frame; a linkage arm mounted for rotating movement on the pivot pin and connecting with the outer sash near the top and the inner sash near the bottom; and a second linkage arm mounted on the pin for rotating movement and connecting with the outer sash near the bottom and with the inner sash near the top, said second linkage arm being hinged at points between the pivot point mounting and the points of connection to the sashes.

2. In a ventilator window the combination of a frame; an inner and outer sash mounted for synchronized swinging movement in said frame; a jamb carried by the frame adapted to engage the outer sash as the latter is moved to a closed position; an integral T-shaped rib extending inwardly around the frame member; a pivot pin mounted on said T-shaped member; a linkage arm mounted for rotating movement on the pivot pin and connecting with the outer sash near the top and the inner sash near the bottom; and a second linkage arm mounted on the pivot pin for rotating movement and connecting with the outer sash near the bottom and the inner sash near the top, said second linkage arm being hinged at points between the pivot point mounting and the points of connection to the sashes.
